G1Megatron question

Alright G1 guys, I need some help. I just acquired one of my childhood wishlist characters in the form of a G1 Megatron. It came with all the accessories, but there was an interesting lack of stickers. Not only lack of stickers,but lack of old sticker residue as well. Obviously, this figure could have simply not had its stickers applied, but there isn't a single Decepticon logo on it anywhere. As I'm looking it over, I notice that it only says "MADE IN JAPAN. TAKARA" on one side by the trigger, without a Hasbro logo. The other side says M.C.12.13 on it. The buttstock has only Takara markings on it, with the years 1974 & 1983. So I guess I'm wondering if this is an early Transformers Megatron, or perhaps something from a line prior to TFs?? If there's something specific I can look at or post a pic of that would help identify it, let me know. I can post pics as soon as I get home from work. Thanks in advance for the help.

I don't think Megs has a lot of stickers to begin with. Maybe the legs and the chest and that is it. If you have an earlier pre-TF version, then I personally don't think you should sticker him up unless you just really want a G1 accurate Megs. I think having a "Man from Uncle" version is way cool.

I would assume that the G1 Megatron figure never had the Hasbro markings on it. I know G1 figures did, but the early (pre-rubsign) versions may not have, as others have suggested, and given the lack of a rubsign or sticker residue, that's the most likely case. I believe the Micro Change one was the same colour, although I could be wrong.

The stock is the handle of the gun. That's the part that Maz is referring to.

Sorry I should have been clearer, the black attachments on the MC version originally formed a sort of firing platform for a Microman figure, but the Megatron can also stand behind it and hold the handles. On the MC version this assembly could fire bullets out too.

I've also been led to believe that the chrome chest of the Japanese UNCLE has a slight gold tint to it, but some owners say that's not the case.

I came across this thread after purchasing a Megatron that was identical in stamping to the one that was posted in the initial question. Did anyone get any further in trying to pin-point when exactly this version was released? I'm still assuming that it was a Transformer vs. Uncle version.

Yeah, my G1 Megatron is exactly the same. Nothing to be worry about as far as I can tell, I've checked most of the reissues and all of them have differences that mark it as different from this one, and of course my own. I'm starting to think earlier releases of Megatron didn't have a Hasbro stamp or stickers. Is it possible Megatron was released with stickers during the cartoon, and this is just a pre-cartoon toy? (Still Hasbro Transformers, but while they were still bringing things into the U.S.) Another thing of note is that the bullets won't fire. If it was a Takara reissue, it would be able to.

E: Actually, I just found mine does have a rubsign. But it still fits the description to a tee about everything else.
